摘　　要：以高价铈盐和季戊四醇为氧化还原体系,引发AM单体自由基聚合,制得星形聚丙烯酰胺(SPAM),并与淀粉接枝得到淀粉改性助凝剂(ST-g-SPAM)。通过FIR对其进行结构表征,并与制得的的聚硅酸氯化铝(PSAFC)铁溶液复配应用到蓝藻废水的处理中,以考察ST-g-SPAM的助凝脱浊效果。试验结果表明,在1L蓝藻废水中投加量为PSAFC4mL,助凝剂16mL时,浊度去除率能达到99%,助凝脱浊效果显著。Acrylamide polymerization was conducted using Ce4＋ and pentaerythritol as initiator systems, and star polyacrylamide（SPAM） was obtained. Graft copolymer of starch with SPAM was synthesized and characterized by FIR. It was compound applied with PSAFC to the treatment of cyanobacteria water to examine its coagulant effect of turbidity re- moval. The removing rate can be up to 99% when PSAFC dosage was 4mL,ST-g-SPAM dosage was 16mL in 1L cyanobac- teria water .
